Specification of Letters Patent;

Application filed April 29, 1920. Serial No. 377,491

I '0 all whom. it may concern:

Be it known that I, PAUL Prnnon, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Beadnumerals of reference marked thereon,

which form a part of this specification.

This invention relates to an improvement in wrapping machines ,whereby the beads of tires to be wrapped are-held closely toward one-another at the timethe spiral wrapping is applied. Heretofoie the tension on the wrapping material has been relied upon to accomplish this, which of course necessitated strong wrapping material. If the beads are not brought closely together when the wrapping is applied, subsequent pressure on the tire causes the'wrapping to be come loose and easily torn. However, if the tire is tightly wrapped with the beads pressed closely together in. the first instance. there is slight possibility of injury to the Wrapping by rough handling of the wrapped tire. i

This invention relates to a means for pressing the tire beads together when the wrapping is applied, a portion of said means serving also to guide the tire into the machine.

It is an object therefore of this invention to provide a guiding and pressing means for a tire when introduced .into a tire wrapping machine, to hold the tire properly situated in the machine and to press the beads tightly together at the time the wrapping is applied. i I Other and further important objects of this invention will be apparent from the disclosures in the drawings and speoiiication. 7

The invention (in-a preferred form is illustrated in the drawings and hereinafter ,more fully described.

Description.

The wrapping machine shown.in Figure 1 briefly described consists of-a base lpro vided with suitable bearings in which ;a drive shaft 2 is mounted. The drive shaft 2 15 provided with a friction driving roll, or

pulley wheel 3 into which a revolvable shuttle 4c engages, to be driven thereby. Said shuttle carries a reel of paper 5. and two reels of cord 6 and 7 for application with the wrapping as shown in Figure 2. Said rotatable shuttle 4c. is not only supported] upon the driving friction wheel 3 but also upon idler guide wheels or rollers 8 respectively, which are mounted on the extremities of a curved U-shaped frame 10 secured upon the base 1. Pivotally mounted on the frame 10 and projecting outwardly and 9 and disposed on the opposite side of said' frame 10, from the guide rolls 8 aud t), are a pair of arms struction, and each provided with a short extension 12 having an adjusting bolt 13 whereby the amplitude of movement of said 1 arms'll toward one another is determined, Each of said arms llis provided with an angled extension 14, as clearly shown inFigure 5, and journalled on each, on a shaft 15, is a convex roller 16 Secured also on each of the angled extensions 14 are a number 0 other shafts 17, 18 and 19 respectively, which are parallel to one another but slightly an-' gled with reference to said shaft 15 and the shaft 18 is elevated beyond the shafts 17 and 19. Pivoted upon the shafts 17 and 19 first mentioned are rollers or guide wheels 20 and 21, and journalled upon the shaft 18 is another roller or guide wheel 22 overlapping the wheels 20 and 21, as clearly shown in Figure 3.

Each of the arms 11, asclearly shown-in Figures 3 and 6, is provided with a lug-23 having a conical insert 24 therein,

or levers ll-similar in con-- and en-' I gaged on said lug and oversaid conical inother end of which engages into insert 27 conical Said tire 34 is sert is a spiral compression spring 25, the

frame and over a conical 26 forming a part of a threaded engaged intoan apertured lug 28 of the frame 10. A frame member 29 is secured on the base 1, as shown in Figure 2, and is provided with an upright 30 having on its upper end a bracket 31 to which is secured a pivotal arm 32 carrying a double guide. roller33 which, when a tire is portion of the member other to-elevate or lower the-tire according nisms from the revolve or'rotatethe tire 34 through to its size into proper position in the eye of the revolvable shuttle 4. However, since this mechanism for'ms 'no part of the present invention, no description. thereof is given but attention is directed to the fact thatthe rolls 35-and36 are driven by suitable mechadrive shaft 2 to continuously the eye of the shuttle applied. thereon.

4 as the wrapping is As shown Figure Idmounted at one side of the wrapping machineis a launching 1 table 40, and

the tire 34 is rolled from j -fthis table in'upright position between the guide rollers 20,21, and 22, over the roller 35 into position on the rollers 35 and36 and'after moving between the guide rolls 20, 21 and 22, shown in' Figure 3, is properly centralized as it drops into position onthe rolls 35 and 36 with the beads of the tire pressed against one another bythe convex rollers 16. r

\ a Operation,

The tire to be wrapped is placedin an upright position on the launching table 40 and then rolled therefromv between the rolls, 20, 21 and 22 over the roll 35 into position resting upon the rolls 35 and 36 and engaged by the pivotally mounted guide roll 33 resting-upon the .upper portion of the tire. Upon the launching table40, it is guided by the pairs of centralizing rollers 20, 21 and 22 which are resiliently mounted on the spring thrust arms 11, and the tire rolls downwardlyto wrapping position through the open hinge section of the shuttle 4 which opens in a manner well known. The tire is supported upon the driving rolls 35 in a counter-clockwise direction. The press'er a recessed j ectionable features within the machine, rests thereon, as;

tire entering the machinefrom the and 36 and rotatesrolls 16 force the tire beads inwardly toward one another in clos relation just before the spiral wrapping is applied. The tight wrapping thus applied serves to hold the beads in this relation and consequently when the tire is completelywrapp'ed, the wrapping cannot become loose, as further compression of the beads toward one another cannot take place. This overcomes the obheretofore encountered when the wrapping was applied upon a tire with the beads not .closely pressed together.

I am aware that numerous detailsof construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by'the prior art.

I claim as my invention:

1. The combination with a wrapping machine for annular objects, of pivotally mounted outwardly flaring aiding arms,

3. The combination with a wrapping machine for annular objects. of resiliently .mounted rollers to guide the object upon introduction into the machineto centralize the object, and-additional resiliently mounted rollers'to press against the sides of the ob- 4.
